I just started a project to make simple socialist flags. The common factor between the flags is, a simple use of the country/place olours flag and a main red element. i have decided to get rid of any other simbol apart from the colours itself to make it even more simple.
In the cases of Ireland and Canada, I decided to keep the simbols for recognizement purposes. For example, Peru has the same color scheme as Canada and the Harp is a universally recognized symbol of the Island.
